Thin, crisp, and packed with chocolate, this brownie brittle is totally addictive!
Carla Hall’s version gets that crispy, chocolatey crunch just right—without tasting burnt or too hard.
A good brownie brittle needs the right balance of sugar and fat to keep it crisp, and this recipe gets it just right.
I always mix the batter well but avoid overbeating—it keeps the texture delicate instead of too dense.
A sprinkle of sea salt on top before baking gives just enough contrast to bring out the richness of the chocolate.

What to Serve with Carla Hall Brownie Brittle Recipe
Mix up your serving options with some unexpected ideas that can make this treat even more fun and enjoyable to serve!
Fresh Berries
Pairing brownie brittle with fresh berries provides a lovely contrast.
The sweet and tart notes from strawberries, raspberries, or blueberries work wonderfully.
It also adds a refreshing element to your dessert plate.
Vanilla Ice Cream
The creamy texture of vanilla ice cream complements the crunchy brownie brittle beautifully.
You can serve it on the side or even put a scoop on top for a fantastic combination.
Don’t forget to drizzle some chocolate sauce if you’re feeling decadent!
Coffee or Espresso
A cup of coffee or espresso is the perfect beverage to accompany brownie brittle.
The rich, bold flavors of coffee enhance the chocolatey notes of the brittle, creating a harmonious pairing.
Experiment with adding a shot of your favorite liqueur to the coffee for an adult twist.
Cheese Platter
A cheese platter may seem unusual, but trust me, it’s an adventure worth trying!
The salty and savory flavors of cheese like brie or sharp cheddar can complement the sweetness of the brittle perfectly.
Throw in some nuts or olives for an extra burst of taste.
Greek Yogurt
For a healthier twist, why not try serving the brownie brittle with some creamy Greek yogurt?
The tartness of the yogurt balances the sweetness of the brittle.
Add a drizzle of honey for an additional layer of flavor.
Variations and Substitutions
Ingredient Swaps
If you’re looking to switch things up, consider trying white chocolate chips instead of dark chocolate.
They bring a unique sweetness that can make your brownie brittle really shine.
You might also want to add nuts, like almonds or pecans, for some extra crunch and flavor.
Texture Adjustments
For a chewier texture, try adjusting the cooking time slightly.
Baking for a minute or two less can maintain a bit of moisture.
For extra crispiness, bake a minute longer.
Flavor Enhancements
Incorporate a hint of espresso powder to intensify the chocolate flavor.
A sprinkle of sea salt on top before baking gives a fantastic contrast and added depth.
Dietary Tweaks
To make it dairy-free, use a non-dairy chocolate and substitute coconut oil for butter.
For a gluten-free version, replace all-purpose flour with a quality gluten-free blend.
These adjustments can ensure everyone can enjoy your brownie brittle!
How to Store Leftover Brownie Brittle
Airtight Container
You absolutely want to keep your brownie brittle as crispy as the day you made it.
The best way to do this is by placing it in an airtight container.
It helps to preserve the texture and keep out moisture that makes it less enjoyable.
Room Temperature
For short-term storage, feel free to keep your sealed container at room temperature.
This method works well for about 3 to 4 days.
If you plan to eat it soon, no need to refrigerate; just grab and go!
Longer Storage Options
If you find yourself with more leftover brownie brittle than you can enjoy right away, consider freezing it.
Place the pieces in a freezer-safe container to lock in that crunch for up to three months.
It’s perfect for enjoying on a later date or surprising a friend with a sweet treat!
Common Mistakes to Avoid
Overmixing the Batter
When you’re making brownie brittle, mixing the batter too much can lead to a dense texture instead of that yummy crisp we’re aiming for.
It’s tempting to get everything perfectly smooth, but stop when it’s just combined.
Using the Wrong Baking Sheet
Not all baking sheets are the same!
Using a dark or non-stick baking sheet can cause the brittle to cook faster, often leading to burnt edges.
I always suggest using a light-colored, heavy-duty baking sheet to avoid this mishap.
Skipping Cooling Time
Patience is key after baking!
Skipping the cooling time can make your brittle soft and limp.
Letting it cool completely ensures it crisps up perfectly before you break it into pieces.
